my code:

<?php
$misspelled = $suggested = $words = array();
$lang = pspell_new('en');

$string = 'Project Engineeer';

echo '<p>Your Phrases was: &quot;'.$string.'&quot;</p>';

$wordlist = preg_split('/[\W]+?/',$string);

for($i = 0; $i < count($wordlist); $i++)
{
      $word = trim($wordlist[$i]);

      if(!preg_match('/[A-Za-z]/',$word))
      {
            continue;
      }
      
      $word = trim($word);
      
      if(!in_array($word,$words,true))
      {
            $words[] = $word;
      }
}

foreach($words as $value)
{
      if(!pspell_check($lang,$value))
      {
            $misspelled[] = $value;
      }
}

foreach($misspelled as $value)
{
      $suggested[$value] = pspell_suggest($int,$value);
}

echo '<p>Suggested words are:</p>';
echo '<ul>';

foreach($suggested[1] as $suggestion)
{
      echo '<li>'.$suggestion.'</li>';
